Here's the Plan

So my book is going to feature full page watercolour illustrations paired with a light facts on space and astronomical objects. The basic journey of the book will be starting at Earth heading towards the Sun by way of the moon, Venus and Mercury then Halley's Comet will take the Spaceman towards the asteroid belt and the other outer planets. Other stops will include the Oort Cloud (the farthest point in our Solar system), a nebula, supernova, blackhole and galaxies.

Here is a outline of most the spreads I'm planning to make...
It's very small and in pencil but I hopefully you can get an idea.
